Fusion of small nuclei (e.g. Deuterium, Tritium) into larger
nuclei (e.g. Helium). As Fusion can only happen at very high
temperatures (i.e., 10,000,000K) it is often referred to as
Thermonuclear Fusion.

Fission explosives are limited in yield by the amount of fuel that
can be placed in the core of the device without risking criticality
before it is desired to have the device detonate (if this happens
the device will most likely just melt and kill anyone nearby). The
theoretical highest yield of a pure Fission explosive is roughly 1
MTon, the highest yield pure Fission bomb tested was a US MK-18
airdropped as the Ivy King shot in 1952, with a yield of about 500
KTons. The core of the MK-18 was a hollow sphere containing
FOUR CRITICAL MASSES of Oralloy (93.5% enriched
Uranium-235). To prevent premature criticality the hollow of that
sphere was filled with a boron/aluminum chain to absorb neutrons,
that was only removed minutes before release from the bomber (this
chain could NOT be put back in to safe the bomb).

Fusion explosives operate on a "Staged" principle: the Primary or
1st stage is a Fission explosive, which emits X-Rays
used to compress and heat the Secondary or 2nd stage
(the actual Fusion explosive). There is no criticality issue with
Fusion, you can make the Secondary almost as big as you want with
as much fuel as you want. If that isn't enough for the yield you
want, additional Fusion stages can be added that are successively
triggered by X-Rays from the previous stage compressing and heating
the new stage. There is no theoretical limit on number of stages,
and the only practical limit is what can fit in and be carried by
the delivery vehicle. The highest yield Fusion bomb tested was the
USSR AN602 airdropped as the Tzar Bomba (King of bombs) in 1961,
with a yield of about 50 MTons. It was a 3 stage device, capable of
a yield of 100 MTons if they had wanted to go all the way.

However, we have a complicating factor, almost no modern nuclear
explosive is pure Fission or pure Fusion. It is often much cheaper,
smaller, and lighter to build for example a miniaturized Fusion
explosive than a pure Fission explosive of the same yield. So, many
Fusion (aka Thermonuclear) bombs actually have far lower yield and
extent of damage than some Fission bombs.

A nuclear bomb and an atomic bomb are virtually synonymous. The twoterms are both used to refer to a nuclear weapon. Even Wikipediaagrees. The use of either term as a search a…rgument redirects theanswer to the article Nuclear Weapon. A link is provided. from benjaminmarkiewicz that dont make any sense a nuclear bombs blow travels 100s of milesand is more powerful cause its the newly invented bomb and theatomic bombs blow travel is under a nuclear bombs travel rate

Nuclear weapons arvastly more danerous than regular TNT because not only do they emit high levels of deadly radiation, which can last for decades, but even the most simple of …atomic weapons, such as those used at Hiroshima and Nagasaki have a yield equivilant to twenty thousand tons of TNT (20 kilotons). Also, if used enmasse, nuclear weapons could cause a "nuclear winter", which would be the result of the dust and smoke created by nuclear blasts, which would fill the atmosphere and block out sunlight, plunging the earth into a long-lasting (I'm not sure exactly how long, but it would be more than years for sure, maybe even more than decades), radioactie winter.

A thermonuclear weapon (Hydrogen bomb) is a weapon whose yield is derived mainly from fusion as its energy source. A nuclear weapon derives most of its yield from fission (som…etimes these are boosted and a small fusion reaction does take place but it's tiny). Typically, these devices consist of a primary and a secondary. The primary is basically a small nuclear weapon. This is exploded and its energy is used to compress a secondary, which contains a source of tritium and deuterium (Li6 Deuteride) which causes a fusion reaction. The primary and secondary are enclosed in a radiation case which focuses the X-rays from the primary's explosion are focused and reradiated, causing the secondary to collapse onto itself, imploding it and causing a fusion reaction. Typically these are found in large strategic and tactical nukes. The yield can be large, or the yield can be small and the weapon small as well.

A neutron bomb is a nuclear bomb. Specifically a neutron bomb is a modified fusion (hydrogen) bomb. In a standard fusion bomb the fusion tamper is Uranium-238. This absorbs t…he high energy fusion neutrons and fissions, producing roughly 90% of the yield of the fusion bomb and most of the fallout. If instead we change the fusion tamper to a different dense metal with a much much smaller cross-section for absorbing neutrons, then most of them escape. This is a "neutron" bomb. If everything else is the same, it has only about 10% of the yield and a tiny fraction of the fallout of the standard fusion bomb (making it a "clean" bomb). Sometimes the neutron bomb is considered an anti-tank weapon, as the neutrons can pass through the tank and irradiate the crew while the lower yield and fallout produce less blast damage and radiological contamination. However the high neutron flux induces secondary radioactivity in most exposed materials. This is also a form of radiological contamination, but cannot be washed off like fallout.

Nuclear bomb can mean either fission or fusion bomb. Hydrogen bomb means fusion bomb. The fusion bomb can be built with any yield one wants, just by adding more stages with mo…re fuel. The fission bomb has a theoretical maximum yield that cannot be exceeded.

still, an normal atomic bomb is more powerful. a thermonuclear bomb can easily take out a base since the thermal energy it produces will easily deep-roast everything it touche…s, but it doesnt turn an entire city into ash in seconds, as do with a normal atomic bomb.

Nuclear bombs release energy from the nucleus of the atom, which is held together by the Strong Force. Conventional bombs release energy from the electron cloud of the atom, w…hich is held to the nucleus by the Electromagnetic Force. The Strong Force is thousands of times stronger than the Electromagnetic Force and thus releases thousands of times as much energy.

They usually have a higher yield. Fission bombs are limited by the laws of physics to about 500kTon to 1MTon yield.Fusion bombs have no such limits, just keep adding stages w…ith more fuel and you can get any yield you want, if you can carry it to the target.

Not at this time, the yield of hydrogen bombs (a type of nuclearbomb) has no theoretical limit. However usable bombs no matter whattype they are have practical limits and we h…ave already built andtested successfully bombs with yields far higher than can bemilitarily practical (nobody ever had a real military use for the50 megaton bomb the USSR tested in 1961 called the Tsar Bomba!). Edward Teller once proposed building gigaton range hydrogen bombs,but the plan was promptly rejected as the vast majority of theblastwave of such high yield explosions would only blow theatmosphere above the point of detonation off into space (themilitary wants surface damage not removal of atmosphere!) producingless surface damage than lower yield less expensive bombs. The trend since the middle 1970s has actually been lower and loweryield hydrogen bombs that when employed as several explosionsspaced across an area produce greater damage more economically thanone higher yield yield bomb could. == In terms of long term damage there are different types of nuclearbombs. Those which spread large quantities of persistent high-levelradiation materials could be argued as "worst" - but they are stillconsidered nuclear weapons. A "dirty bomb" which simply uses aconventional explosive to spread radioactive materials over a widearea to contaminate it could possibly be considered equally bad.

Nuclear bombs use nuclear fission of some heavy element, usually uranium or plutonium. Thermonuclear bombs use the detonation of a fission bomb to ignite the fusion of hyd…rogen. Such weapons are more powerful than ordinary nuclear weapons because nuclear fusion releases more energy than nuclear fission, and because the process of fusion itself can be used to ignite more fission.
